Abstract: We studied the electronic structures of LaOFeP under applied pressure usingfirst-principles calculations. The electronic density of states at the Fermilevel decreases continuously with increasing pressure. The electron branches ofFermi surfaces are rather robust to pressure, while the hole branches changesignificantly. Two hole surfaces shrink into small ellipsoid-like surfaces anddisappear finally, at which the applied pressure is ~ 74.7 GPa. The pressureresponse can be understood by the band structures around the Fermi level.Comparative studies reveal that the disappearance of hole surfaces is mainlydue to the compression of the FeP layer along the c-axis of unit cell.
